1 MOPfWIRINGER- Specification of Letters Patent. l Patented-August4, 1908. Application led February 6, 190,6.` Serial No. 299,695.

To all whom it may concern: i

Be it known that I, WILLIS H. WETMORE,

of Oneida, in the county of Madison and State Vof New York, have invented certain thereof, which will enable others skilled in the art to which it appertains to make and4 use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification. i

The object of my present invention is to provide an improved mop Wringer., which is simple in construction, cheaply manufactured and effective in operation.

Inthe drawings Figure 1- shows an end view of a mop wringer of my improved construction having the end frame `on the inner side removed and certain ortionsshown in section. Fig. 2 shows a si e elevation of the wringer, being the same as seen from.the

right of Fig. 1. Fig. 3 shows a partial horizontal section of the wringer.

Referring to the .reference letters and figures in a more particular description, 1, 1 indicate the two end frames, each of which 1s provided with a comparatively large downwardly projecting portion la adapted to enter and engage on the inner face of a bucket or pail to which the'wringer is ada ted to be applied, while 1b indicates the sma ler downwardly extending projection on each end frame adapted to engage the outer wall of a bucket or pail in securing the wringer in position thereon. At one' side of the end frames there is located and secured rigidly thereto a fixed presser board 2, while at the opposite side of the frames 1 and mounted in bearings to rock therein, there is provided a shaft 8. Located between the presser board 2 on the one side and the rock shaft 3 on the other is the movable follower 4. The bottom, as between the stationary press board 2 and the follower 4 in open position, is closed by a bottom piece 5. On its opposite ends the movable follower 4 is provided with rojections 6, which are arranged substantlally in the middle line of the follower and engage in slots or ways 7 in the end frames 1 whereby the follower. is supported for transverse movement across the frame towards the stationary presser board 2 and is free to swing on the projections 6 as a pivot to a limited extent, whereby the follower will automatic ally adjust itself to the mop inserted rbetween the follower and the stationary presser board 2, .Y y

For operating the follower 4 there are provided on the rock shaft 3 a pairof arms 8 located adjacent to each end of the follower 4 and connected at ,their swinging ends by connecting rods 9 with the said pivotal projecl tions 6. The arms 8 are rigidly attached to the shaft 8 so that thearms at each end of the wringer movesimultaneously causing the follower to, move at cach end uniformly across and back in the frame. For operating the arms 8' and thev connecting rods 19, there is provided on one end of the wringer an operating lever 10. The lever 10 is pivoted at 11 independently at one end to the frame and is provided with a projection 10a having a slot 1()b which receives the extended pivotal pin of the joint ybetween one of the connecting rods 9 and its corresponding arm 8. The length of the projection 10a and the shape Of the arm 10 is such that when turned over into the position shown in dotted lines in Fi 1, the arm 10 will not come in contact wit the up er edge of the presser board 2 before the fol ower has attained its closed position. Preferably at this time the toggle joint made by the arm 8 and the connecting rod 9 will be in a straight, or a substantially straight sition. It will be noted by reason of tIiis fact, the swinging movement of the follower against the presser board at its limit of movement is slow and powerful, while in the initial movement towards closed position the movement of the follower is comparatively rapid and considerably less powerful. This varticular arrangement of rock shaft, rock shaft arms, connecting rod and operating lever is very effective for operating the movable follower without danger of binding in the frame.

To .insure the follower 4, assuming the proBper open position, as shown particularly in ig. 1 when the parts are moved to open position, there is provided on oneof the end frames (or for that matter both) a stop 14 against which the lower corner of the follower is adapted to`strike and which will serve to bring the follower into correct open osition in case it has a tendency to open otherwise, whichl mayl occasiona y occur.

The station ry presserV board 2, as well as the follower' 4, are provided with o enings 12 for the escape of water expressedp from the mo These openings are given a downward inc ination, as shown for two purposes: first--to direct any Water that might otherwise tend to spirt horizontally out from these openings, and perha s not be caught in the pail or bucket lto which the wringer is attached, in a downward direction into the pail or bucket. And secondly-to eliminate a pocket which will retain water which has been expressed from the mop until the pressure is relieved, when the water will immediately be again absorbed from the pocketsV into the mop. If the openings have a sharp downward inclination, as shown, the contents of the hole is drained out by gravityT promptly and is not again absorbed by the mop, as before suggested.

What I claim as new and desire to secure by Letters Patent is:

1. The combination in a mop wringer, of end frames provided with means for engaging the edge of a pail and each having a transverse s ide way therein, ixed presser board and bottom piece bothl secured in osition between the end frames, a movable ollower having pivotal projections engaging in said transverse slide ways, a rock shaft mounted in bearings in the end frames and having crank arms, connecting rodsconnecting the swingin ends of. said crank arms with the said fol ower projections severally, and an operating lever pivoted independently to the frame and connected to the joint between one of' the said crank arms and its connecting rod, substantially as set forth.

2. The combination in a mop wringer of end frames provided with means for engaging the edge of a pail and each having a transverse slide way therein, fixed presser board and bottom piece both secured in position between the end frames, a movable follower having projections engaging in said transverse slide ways, a rock shaft mounted in bearings in the end frames and having crank arms, connecting rods connecting the swinging ends of said crank arms with the said fodlower projections severall f, an operating lever pivoted independently to the frame and connected to the joint between one of said crank arms and its connecting rod and a f stop arranged to engage the lower edge of the follower in its opening movement and throw it into proper open position, substantially as set forth.

In witness whereof, I have aliixed my signature, in presence of two witnesses, this 31st day of January, 1906.

WILLIS H. WETMORE.
